Waste Treatment Concerns• SHE (Safety, Health, Environment) Compliance• Odours/Overflows• Complaints• Costs

– Out of Compliance Fines/Reputation– Pump out/Disposal charges– Clearing Line Blockages– Trap/tank/line Maintenance and repairs– Treatment costs/Utility Bills


Organic Waste Treatment Options

• Equipment : grease traps, septic tanks, DAF etc• Commodity Chemicals• Coagulants, Flocculants, Surfactants/Enzymes• Bacteria: Dry/Liquid• BioGenerators

What’s the difference?What’s the difference?


What’s the difference?• Chemicals

– Caustics/ strong acids/surfactants react with grease to form soluble compounds and generate heat to soften it and move it downstream

– Potential Risks to personnel, environment and downstream blockages

• Enzymes– Organic (protein) molecules that catalyse chemical breakdown of long chains to smaller ones.

Each enzyme unique shape to work on one substrate eg Amylase for Starch breakdown to glucose.

– Enzymes are NOT alive and so can not reproduce. Risk that long chains will reform downstream and cause blockages. No effect on Phosphates, Nitrates etc.

• Bacteria– Living cells that reproduce by generating enzymes to break down the long chain waste molecules

to shorter forms and then consume the shorter molecules and reduce them to water and CO2. Also consume any Phosphates, Nitrates, Ammonia in waste

– No risk of downstream blockages, environmentally friendly

• BioGenerators– Pre-grow tailored Bacteria in ideal conditions: nutrient, aeration, so huge colonies of fully active

Bacteria are dosed automatically– Most effective and economical way to dose Bacteria


Biological Products are NOT “all the same”

• Bacteria/other constituents– Physical form: Solids, Liquids– Type and Number of Strains– Concentration/Activity/Shelf life– Nutrient content– Enzymes, surfactants and other chemicals in Blend

• Cost /Price – Product Price vs Cost in use vs Performance

• Application Equipment– Pumps/timers– BioGenerators: Grow tailored Bacteria in ideal conditions: nutrient, aeration, so huge

colonies of fully active Bacteria are dosed automatically and ready to work immediately!


BioGenerator Basics

Highly active Tailored Bacteria


BioGenerator-Bacteria• Most commonly Bacillus strains because they can be stored as stable,

tough, long shelf life liquids, with Bacteria in Endospore form:• Subtillis, Thuringiensis, Licheniformis, Megaterium, Stearothermophilus,

Polymyxa, Pumulis

• Many other Bacteria can be used depending on nature of waste to be degraded including Pseudomonas Putida, Fluorescens, Stutzeri, ThioBacillus, LactoBacillus, Cellulomonas uda and more!

• Bacteria produce:• Natural Surfactant (Surfactin)• Wide range of enzymes

• Lipase: FOG• Amylase: Starches• Protease: Proteins• Cellulase: Paper/Vegetables• Ammonease/Reductase : Human/Animal wastes


BioGenerator-Nutrient

• For optimised performance, nutrient must sustain growth, activity and quality of the bacteria

• Nutrient should include• Carbon source: Carbohydrates eg sugar• Nitrogen Source: Organic eg Amino acids/Protein• Phosphate/Potash/Micronutrients• pH regulation


BioGenerator-Aeration

• Bacillus strains are facultative Aerobes, so can cope with low/no oxygen, but grow FAR more effectively when correctly aerated.

• Pseudomonas strains are obligate Aerobes and must be aerated or will die

• O2 level should always be >2mg/litre• O2 consumption 3-20 ml/litre/min• O2 replenishment comes from surface in still

solutions and from entrained bubbles in turbulent/circulated solutions


BioGenerators-An innovative approach

• Work WITH any existing treatment equipment• Effective

– Tailored Bacteria (Active, Robust, long shelf life)– Variable nutrient regime– Aeration

• Low Capital cost vs other WWT options• Low operational cost

– Less Bio feed for given Bio activity– Low/No mains power, small/no pumps: can be driven by mains water

pressure and battery powered controller– Robust, unique design ensures Minimal maintenance

• Flexiblility– Waste type, flow rate, surges– Alignment to CIP/cleaning regime
